Cayenne pepper cranks the sauce up to 800 Scoville units of heat compared to Taco Bell's Fire Sauce at 500 Scoville units, which makes this the hottest stuff you can get at the chain. Now, with this secret formula, you can adjust the heat up or down to your preference just by playing with the amount of cayenne you add.
The Guinness World Record for hottest pepper has changed hands several times since 2011. The hotness of peppers is measured in  Scoville units.. Tabasco sauce is typically 2,000 to 5,000 Scoville units. Take a bite out of a jalapeno pepper and you'll be exposing your tongue to up to 10,000 Scoville units. While for most people that's hot, it's only a fraction of the spiciness found in some of the world's hottest peppers. For instance, a typical habanero pepper, which can be found in many local grocers, can be up to 35 times as hot as the hottest jalapenos and 70 times as hot as Tabasco sauce, clocking in at the high end at 350,000 Scoville units.
